Is Meta down, or is it my account?

When performance falls off a cliff overnight, it is often a Meta-wide delivery or reporting outage, not something you did.

1. Look for a platform-wide pattern: a sudden drop across every campaign at once, and others reporting the same on status trackers and the ad forums.
2. Separate a delivery outage from a reporting one: if spend and impressions look normal but conversions or purchase events flatline, it is tracking, not delivery.
3. Hold, do not react: avoid budget, targeting and creative edits during an outage, because they reset the learning phase and cost you when delivery returns.
